Explanation:
We cannot possible determine the exact location to find the math class, since we are only given the condition of having 10 doors and only 2 doors have a math class. Hence, we can equate it as a probability of opening a door by which has math class on it.
Solution:
We can equate it by dividing the number of doors that contain math class, with the total number of doors.
= 2/10
= 1/5
= 0.2
Since we are given a decimal answer, in order to convert it into percentage, we multiply the decimal by 100. Hence, in converting a percentage into decimal, we divide the percentage by 100.
= 0.2 (100)
= 20%
Final answer:
The probability of opening a door that has math class is 20%.
